Feature:1. CONVENIENT and PRACTICAL: The relay module can realize the fast and frequent switching on and off of the circuit at high frequency2. STABLE OPERATION: No noise will be generated during the on and off process, giving you a quiet working environment to meet your daily use needs3. 32 KINDS of FUNCTIONS: 32 kinds of commonly used functions can meet the needs of more applications, and can control solenoid valves, water pumps, motors, light strips, etc4. SAFE and RELIABLE: There will be no electric sparks or electromagnetic interference during use, so you can use the relay module with confidence5. LONG SERVICE LIFE: The service life is longer than that of common electromagnetic relays and can completely replace electromagnetic relaysSpecification:Item Type:Relay ModuleProduct Model: YF-11Input Voltage:DC7~24VOutput Power: Can Control DC Power Load within 10ATime Range: 0.01 Second to 999 Minutes, Any Time AdjustableFunction: Pulse Trigger Cycle, Timing, Delay, Power Tube, mos Tube, Field Effect Tube, Switch, Relay SwitchApplication: It is Often Used to Control Motors, LED Light Strips, DC Motors, Micro Water Pumps, Solenoid Valves, Etc.P-21: Give the signal, after a delay of A second, the output startsP-22: Give the signal, after more than A second, the output starts, the signal disappears, and the output stopsP-23: After the signal disappears for more than A seconds, the output starts, there is a signal, and the output stopsP-24: There is a signal. After A second, the output starts, and after the signal disappears for more than A second, the output stops.P-25: When there is a signal, the output will start after A second, and the output will stop when there is another signal for more than A secondP-26: There is a signal, the output stops after A second, and the signal disappears and the output stops after A second.P-27: Detection of a pulse signal, the output stops; no pulse signal, more than A second output start; (the signal continues or the signal disappears are regarded as no pulse signal)P-28: After power on, after a delay of A second, the output starts until the power is offP-31: After power on, the output starts for A second, stops for B second, infinite loop; power off stopsP-32: When there is a signal, start P-31 infinite loop; when the signal disappears, terminate the loopP-33: Give a signal to start P-31 infinite loop; give another signal to terminate the loopP-34: After power-on, after a delay of A second, the output will start, and it will stop after closing B secondsP-35: There is a signal, after a delay of A second, the output will start, and it will stop after the pull-in for B secondsP-36: There is a signal, the output will start after A second, and stop after B second, the signal disappears, and the timer will be cleared and stopped.P-37: When there is a signal, the output starts and stops automatically for A second, and then counts for B seconds after it stops. The signal trigger is invalid within A+B timeP-38: There is a signal, the output starts and stops automatically for A second, after stopping and counting for B seconds, restarting for A second automatically stopsP-41: No action with signal; trigger when signal disappears; disconnect after output start delay A timeP-42: The signal disappears, after a delay of time A, the output starts; working time B endsP-43: The signal disappears. After the time A exceeds, the output starts; the working time B endsP-44: After power on, the output will start A time, stop B time; cycle C times and automatically stop.P-45: No action when energized, after signal is given; output starts A time, stops B time; cycle C times and automatically stops; Give signal again, execute againP-46: After giving the signal more than A times, the output will start; keep the output; stop when the power is offP-47: After giving the signal more than A times, the output starts and stops for B secondsP-48: Within C seconds, after continuously giving the signal more than A times, the output starts and stops in B seconds3. Description of button setting:Power on display "" means entering standby state;Press K1 for the first time, (it takes more than 1 second to be effective to prevent false triggering) Display: P -11: K2 adjustment main mode, K3K4 adjustment functionPress K1 for the second time, the screen displays: A001: K2 and K3 adjust the first time A, K4 adjusts the decimal point (time unit)Press K1 for the third time, the screen displays: B001: K2 and K3 adjust the second time B, K4 adjusts the decimal point (time unit)Press K1 for the fourth time, the display "" means entering the standby statePress K4 in standby mode to permanently turn off/on the display and switch to low power consumption mode4. The decimal point time unit description:X.XX The decimal point is in hundreds, and the timing range: 0.01 seconds to 9.99 secondsXX.X The decimal point is in the tenth place, timing range: 0.1 second to 99.9 secondsXXX has no decimal point, timing range: 1 second to 999
